Source records

This activity is assembled from 31 catalogued encounters on Happywhale.

Sighting records from Happywhale, published as occurrence data via GBIF. Individual records are licensed CC0 1.0, CC BY 4.0 or CC BY-NC 4.0, depending on the contributor.

The photographs and fluke identifications behind every sighting are the work of the contributing observers — the citizen scientists, naturalists and operators who logged them, each named in the underlying GBIF occurrence record. Every activity links out to its source encounters on Happywhale. Basemaps © OpenStreetMap contributors (ODbL).
